• Updates the value at given path of given object. It mutates the object. If path is not found then objects are created "on the way". If non-objects are found, they are replaced with new plain objects. If primitives are used as source they are ignored and returned value is empty object with updated value at given path.

    Example

    set(object, "deep.property", value)
    

    Example

    set(object, ["deep", "property"], value)
    

    Example

    set({}, "deep[0].property", value)
    // will create this structure:
    { "deep[0]": { "property": value }}

    Example

    set({}, "items.0", value)
    // will create object, not array
    { "items": { "0": value }}

    Returns

    • given object or new object if source was primitive
